Gohn, Grosse Ile, Mich. I I IApplication October 26, 1945 SerialNo. 624,810 7 Claims. (01. 48-180) Myinvention relates to a 'newand useful improvement in a gaseous fuelmixer and more particularly to a mixer that is readily mounted between acarburetor and intake manifold without interference with th presentparts of an internal combustion engine.

It is an object of the present invention to provide'a mixer of this kindwhich operates through the suction of an internal combustion enginetobreak up all liquid globules into gaseous vapors and thoroughly mixingit with air passing therethrough from carburetor to the intake manifold.

Another object of the present invention; is to provide a mixer which'will readily revolve and break up any liquid globules passingtherethrough and providing a central passageway through the mixer forpassage of gaseous mixtures therethrough and which serves as an axis forthe revolving mixer. I II A further object of the present invention isto provide a mixer with a rotary member having a plurality of angledpassageways therethrough connecting with similarly directed passagewaysin a stationary member which serves to jet the gaseous fluid as itisforced therethrough by the rotating member into the intake manifold.

A still further object of the present invention is to provide a mixer ofthis class which is simple in structure, economical of manufacture,durable, compact, highly efficient in use and easily installed.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made inthe detail of structure illustrated and it is intended that such shallbe embraced within the scope of th claims which form a part hereof.

Forming a part of this specification are drawings in which,

Fig. 1 is'a central vertical cross-sectional view of the inventionshowing it installed between carburetor and intake manifold,

Fig. 2 is a view taken along line 2-2 of Fig. 1,

Fig. 3 is a sectional view taken along line 33 of Fig. 2,

Fig. 4 is a fragmentary bottom plan view of the invention.

Shown in the drawings is a plate II! which is interposed in theconnection between the carburetor outlet conduct l I and the neck I2 01'an intake manifold and is secured therebe tween by the bolts l3. Theplate I0 is provided with a circular recess or well H which is in directcommunication with the outlet side of the carburetor, and provides athin wall [5 on the intake manifoldside, Positioned in the recess orwell I4 is a disc N5 of slightly smaller diameter than the recess orwell M to permit free rotation of the disc therein. Centrally located inthe disc I4 is an axially directed passageway 11 which communicates.with a similarly directed passageway I8 formed in the wall H) of plateI0. Grouped radially about the center passageway I! are a plurality ofpassageways l9. These passageways 19 are grouped in concentric circlesabout the passageway I1, and a similar number of pas-J- sageways areformed in. each concentric circle. The. passageways are uniformlyspaced-apart in each concentric circle,v and further in each circle thepassageways are staggered relative to the preceding circle when countingoutwardly from theinner circle. Thus' the passageways on theintermediate row will be set rearwardlyto respec-:, tive passageways onthe adjacent inner row rela-. tiveto the direction of rotation of thedisc.

Similarly the outer or succeeding concentric circle of passageways willbeset rearwardly to respective passageways on the intermediate row .1relative ftosthe direction of rotation of .the disc- The radial anglesbetween respectively staggered. passageways in. theinnercircle with theinter-.L mediate .circle,.and between the intermediate cira:

of the disc, and all are directed at the same angle. Each of thepassageways 19 are further directed tangent to its concentric circle. ,7A similar number of passagewaysZOare formed in the thin wall Thepassageways 20 are arranged :in identical manner to those in the sectionI5 of the platelfl.

Formed the periphery of the disc l6 are grooves 2|. The grooves 2| areequally spacedapart and-areform'ed atan inclined angle identical to theangle of the passageways l9.

grooves 2! acts as a cushion and lubricant for" the rotating disc 16,between its peripheral sidesf i and the sides of the well l4.

To prevent the rotating disc from bobbing up" and down in the well M duetq-any undue vibra tion of the internal combustion engine there isprovided a thin plate 24 secured between plate Ill and carburetor andwhich extends over the peripheral edge ofthe disc to prevent the disc Hifrom moving outwardly from the Well.
